摘要: Abstract Antireflective coatings with adjustable transmittance and high laser-induced damage threshold (LIDT) have been prepared by the deposition of magnesium fluoride (MgF2) nanoparticles on fused silica substrates. The peak is 99.98%, mainly due to low refractive index caused introduction porosity between MgF2 nanoparticles. With varying coating thickness, optimized antireflective performance at any wavelength 300 1100 nm can be achieved. effect particle size properties has also investigated. from small particles exhibit higher short wavelengths than do large particles. LIDTs 351 nm, 527 nm 1053 nm are 25 J/cm2, 34 J/cm2 63 J/cm2, respectively. LIDT attributed band gap MgF2. may potentially applied in high-powered lasers.
